Lime Slurry Batch Mix Tank Ultrasonic Level Measurement_________________________________________________________________
When an Ohio water treatment plant needed reliable level measurement of their lime slurry mix tank, they turned to Flowline. Slacked or hydrated lime is used by the plant for water or chemical precipitation, coagulation, neutralization and stabilization. Lime slurry is notoriously messy with dust plumes, splashing and material buildup left on anything it contacts, including level sensors. Plant operators would make a batch and use a dipstick to manually check the level as feed pumps drew lime from the tank. But this led to lime shortages and process shutdowns. For this reason, Flowline suggested the use of our non-contact ultrasonic sensor, inserted through a hole in the tank top with two feet of excess cable. This allows the sensor to be periodically lifted, easily wiped of any buildup and placed back onto the tank. The ultrasonic sensor provides continuous level data to the SCADA system, which monitors the tank and alarms for replenishment. Flowline is reliable level measurement. |
Zoo Animal Exhibit Tank Level Ultrasonic Level Measurement_________________________________________________________________
When the Saint Louis Zoo needed reliable level measurement of their animal water exhibit tanks, they turned to Flowline. The exhibits are largely open to the environment, subject to rain, snow and significant temperature swings. The primary level challenge is evaporative water loss, accelerated by heat in the summer, or condensing morning fog in the spring, winter or fall. Depending on their size and exposure, exhibits lose up to 500 gallons per day, which must be automatically detected and replenished. Zoo staff were dissatisfied with a different brand of ultrasonic level sensors, that became intermittent, when condensation formed on their transducers, and attenuated their acoustic signals. For this reason, Flowline suggested the use of our reflective ultrasonic sensors that are unaffected by condensation. The ultrasonic sensors provide continuous level data to the PLC, which monitors the exhibits and controls the fill valves. Flowline is reliable level measurement. |
Tannery Wastewater Screen Tank Radar Level Measurement_________________________________________________________________
When an Arkansas tannery needed reliable level measurement of their pre-treatment tanks, they turned to Flowline. Tannery effluent is filled with organic material and suspended solids that must be screened and removed prior to treatment. The resulting wastewater pours into a collection tank with the consistency of watery cake batter. Laden with chromium salts, a primary tanning chemical, the media is coating, corrosive and sometimes foaming. Plant operators complained that past guided wave level sensors only lasted a year due to corrosion, and ultrasonic level sensors became intermittent whenever surface foam developed. For these reasons, Flowline suggested the use of our non-contact radar sensors that are unaffected by the surface characteristics of the liquid. The radar sensors provide continuous level data to the tank indicator and PLC, which controls the waste screening and transfer. Flowline is reliable level measurement. |
Carbon Powder Mix Tank Level Ultrasonic Level Measurement_________________________________________________________________
When an Oregon water treatment plant needed reliable level measurement of their carbon mix tanks, they turned to Flowline. During the hot months of summer, reservoir temperatures rise. Concurrently, water inflows contain unusually high levels of algae and other organic compounds that negatively effect water quality, taste and smell. To combat this, the plant injects activated carbon solution into the water that naturally absorbs organic material. Carbon batches are made up in mix tanks that blend water and carbon powder into solution. Plant operators were dissatisfied with previous float level switches that would often stick due to material build-up, and required frequent maintenance. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors that are unaffected by coating liquids. The ultrasonic sensors provide continuous level data to the relay controller, which automatically makes up each batch. Flowline is reliable level measurement. |
PH Neutralization Skid Tank Ultrasonic Level Measurement_________________________________________________________________
When a California manufacturer of water and wastewater treatment equipment needed reliable level measurement of their pH neutralization skids, they turned to Flowline. The firm supplies a variety of fluid handling skid types and sizes for chemical feed and water or wastewater treatment, with the common denominator of corrosive, coating and dirty liquids. Given the diversity of liquids, tank sizes and measurement or switch requirements, the company used three different level sensors across their systems. Additionally, sticking level switches due to coating build-up was their top unpaid warranty service call. For these reasons, Flowline suggested the use of our non-contact ultrasonic level sensors that work maintenance free across their liquids and tank sizes with both analog and switch outputs for field replacement. The ultrasonic sensors provide continuous level data and/or programmable relay outputs to the PLC, which controls the skid. Flowline is reliable level measurement. |
Petrochemical Reactor Waste Tank Radar Level Measurement_________________________________________________________________
When a Texas petrochemical manufacturer needed reliable level measurement of their reactor waste streams, they turned to Flowline. The company produces rubber, plastic and resin polymers that are applied in industrial and consumer products. The hazardous reactor tanks generate corrosive wastewater, laced with spent acids, particulates, steam and condensation. At the end of each batch cycle, the residual contents are transferred to a bulk storage tank for neutralization. There plant operators were dissatisfied with a different radar level sensor brand, that performed intermittently during peak condensation, and failed after nine months due to corrosion. For this reason, Flowline suggested the use of reliable radar sensors with rugged condensation shedding PTFE antennas. The radar sensors provide continuous level data to the SCADA system, which monitors the levels and controls the process. Flowline is reliable level measurement. |
Farm Irrigation Canal Weir Ultrasonic Level Measurement_________________________________________________________________
When a California farm company needed reliable level measurement of their irrigation canals, they turned to Flowline. Water supply and distribution is critical to their farm business, and they manage it through automation. Pumped from the California Aqueduct, water traverses through main canals that feed individual crop fields. The canal levels are measured as the water passes through weirs, and flow data is transmitted via a LoRa wireless network to a central monitoring station. Farmers complained that previous ultrasonic level sensors became intermittent when morning fog, rising off the water, condensed droplets on the transducers. For this reason, Flowline suggested our proprietary reflective ultrasonic sensors that are unaffected by condensation. The ultrasonic sensors provide reliable level data to the farm operators, who monitor and control water distribution. Flowline is reliable level measurement. |
Foaming Concrete Wastewater Tank Radar Level Measurement_________________________________________________________________
When an Ohio precast concrete manufacturing company needed reliable level measurement of their wastewater collection tanks, they turned to Flowline. The firm makes molded catch basins, curb inlets, water meter and utility vaults for city clients throughout the Midwest. Concrete is made, poured into forms, dried, released and stacked for shipment. At the end of each batch, the equipment, forms and shop floor are washed, and the waste is transferred to a collection tank for treatment. There the operators complained that past ultrasonic level sensors were unreliable due to agitation, foam and material build up resulting from splashing. For this reason, Flowline suggested the use of our radar sensors that are unaffected by agitation, surface foam or build up on the antenna. The radar sensor provides continuous level data to the indicator and PLC, which controls waste transfer and treatment. Flowline is reliable level measurement. |
Aerospace Scrubber Sump Ultrasonic Level Measurement_________________________________________________________________
When a Northeast aerospace manufacturing firm needed reliable level measurement and control of their scrubber sump tanks, they turned to Flowline. Prior to safe release, gas waste streams with spent sulfuric acid are neutralized with sodium hydroxide in large wet scrubbers. Water recirculating through each system is constantly evaporating, and must be replenished several times a day. The operators complained that past float and conductance level switches often failed due to scaling caused by the high salt content of the water. For this reason, Flowline suggested our non-contact ultrasonic sensors with embedded relays and control logic. They simply configured the relays to mimic the previous switch points with a non-contact level switch, and problem solved. The ultrasonic sensors provide reliable water level detection, solenoid control and alarms. Flowline is reliable level measurement. |
Water Treatment Skid Tank Ultrasonic Level Measurement_________________________________________________________________
When a European manufacturer of water treatment equipment needed reliable level measurement of their neutralization tanks, they turned to Flowline. Their portable systems reclaim, neutralize, filter and return process water back into use, lowering water consumption and prolonging the life of wet process equipment. Prior to membrane filtration, acid and lime are dosed into the stage one mix tanks. There the engineers were dissatisfied with previous ultrasonic level sensors that became intermittent whenever condensation droplets formed on the transducers, attenuating their acoustic signals. For this reason, Flowline suggested the use of our proprietary reflective ultrasonic level sensors that are unaffected by condensation. The ultrasonic sensors provide reliable level data to the PLC’s which control each skid. Flowline is reliable level measurement. |
